Eos'rnnn, citizens oigthe United States, 'residing Uhicago, in thecountyo Cook and State of Illinois, inve -invented va 'certain new and 'useful Improvent in Apparatus, of which the followisa speciiication. i

the current of impure airit maybe developed ach manner to kmake its constant inspection easy etiective. l l Y I, Oneiorin ci my deviceds illustrated in the accomel; rs l. is a longitudinal-vertical section, and

is cross section on the h'ne'2-2.

i ereby, without obstructing1 interfering wither im` the figures.

Ii is s'. base plate vpreferably o metal.

f E are. interchangeable end pieceseach cupshaped crm and provided -with alpipe connection and .i :lng B1 and a supporting legB2.

C is a glasscylinder-:bearing at each end' on the G1 placed in a suitable recess formed in' itshorizontal position as shown.

The use and operation of our device are as ollows: The current oi impure or dust ladened air can be passed through the device` in either direction. 'We have assumed that it takes lthe course indicated by the arrows, in whichevent it enters one of the endpieces' tangentially., passing around `the inner surface' oi such.

end pieces, then passing around the innersurface of the glass cylinder, and thenaround the innersuracef ci? the other endpiece and 'out through its opening.

The action of the 'current of air is such that inthefirst piece the hard metalor other pieces therein contained and thereby are set into a swirling motion before thyencounter the inner surface ofthe cylinder. This prevents the'` breakage of such 'cy1inder.`v The 50 next action of the current of air is to keep the-inner Lise parte are indicated by thesame letter in'all surface 'ofthe cleanibe'cause in its progress through, thej'sanie'uit tendslm strike such surface* and l rub or polish the samefwhich is not the case where the 'current oiiairgis proceeding in a'direc't forward -nianner through a section'oi glass tubing.' In the. 'nextfplace becauseV the current of is thus concentrated, or a series of its convolutions sc to speak are' Sur invention relates to an attachment for air puriig apparatus and has inrit-s object to provide means' concentrated in a singlefdeiinitespace, the air and its impuritiesor dust maybe inspected: .Broadly speaky ing there is no real interruption of. the current.v The current simply passes on' a circuitous routey through an inspection chamber or section.

We claim:

In a fluid inspection device comprising a partially transparent 'chamber forming Ypart of the fluid passage- 4 vWay and having an inleadng opening adapted/ to dis- `charge into such chamber tangentially to the inner surface'v thereof.'

2. A fluid inspection device comprising a partially trans` v piece of said chamber tangentially to the inner surface thereof. l

4. A uid inspection device comprising a partiallyv transparent cylindrical chamber. with metallic V, cup-like l end pieces forming part of -thex uid passage-Way and having each 'an opening adapted to discharge into 'such end piece of said chamber tangentially to the inner surface thereof.

5. A iuid inspection device comprising a partially transparent chamber, with an opening at eachend adapted to discharge' into said chamber tangentially to the inner surface thereof.

6. A uid inspection device comprising a cylindrical. v *transparentA inspection chamber with .metallic end 'pieces each having an opening which enters tangentially, and means for securing the whole together.

7. A uid inspection device comprising a cylindrical transparent inspection chamber vwith metallic end pieces each having an opening which enters tangentially,` and means for' Securing the. whole together consisting of an axial rod passing through and secured to the outside of the end pieces. 'A i 8. A iiuid inspection device comprising ya cylindrical chamber approximately at 'right angles to the directionV of current, provided with openings lat its two ends which openingsv enter into the' chamber tangentially.
